The battery fuse protects the wiring — not the devices connected to them. When replacing lead-acid batteries with lithium (LiFePO4), a suitably rated primary battery fuse is essential. Its critical role is to protect the system from catastrophic short-circuit events. Unlike lead-acid batteries, LiFePO4 cells have extremely low internal resistance and in a dead-short scenario the battery can release many thousands of amps almost instantaneously for a split second. Without adequate protection, this can vaporise cables, potentially resulting in fire. This means the fuse protecting your old lead-acid battery is no longer suitable. It will need replacing. You are likely to have a MEGA, MIDI or a BLADE fuse which are not appropriate for protecting Lithium batteries. MEGA, MIDI or BLADE fuses are ideal for use with Lead-acid batteries and protecting loads from chargers. But they do not have the right blowing characteristics to protect your system from the power of a lithium battery.
LithiumPro Batteries have very powerful and advanced Battery Management Systems (BMS) that are designed to protect against short circuit, reverse polarity and over current scenarios but this is NO substitute for having a correctly sized mechanical primary battery fuse in a dead short scenario.
Its critical the fuse has a fast-acting element and the appropriate Ampere Interrupt Capacity (AIC) designed to blow quickly and safely opening the circuit so the current can no longer flow. High quality MEGA and MIDI fuses only have a maximum AIC rating of 2000A which is not high enough to support lithium systems.
For safety and compliance, only use reputable fuse brands such as Blue Sea, Bussmann, Littelfuse, Mersen or Siemens with high AIC capacity ≥6000A. Never use cheap fuse alternatives from market places without datasheets. Original Equipment fuses will have the specification marked on the fuse itself. – High quality fusing is the most safety critical component in your whole electrical system.
Want to understand more about fusing READ MORE in our Essential Guide to Fusing Lithium Batteries
For our drop-in-replacement range of batteries with capacities up to 180AH we recommend the MRBF fuse kits as they can be secured directly to the positive battery terminal which offers the safest approach – by not leaving any cable exposed without being fused. They also have a high AIC rating of 10,000A which is essential to protect your system. Given the ‘drop-in-replacement’ range are often placed in height sensitive locations an ANL fuse & holder would also be an suitable alternative as long as it has and AIC rating of ≥ 6000A. Always check the fuses manufacturers datasheet for the Ampere Interrupt rating.
For our larger capacity batteries such as the 460AH-650AH we only recommend using a Class T or NH fuses.
Ensure you protect your lithium battery and the system by adding a high-quality primary battery fuse with the a suitable interrupt capacity. IMPORTANT: Only use notable brand fuses and not cheap fuses from various online market places.
